Rapacc, the world where the Paccosh species resided, was a planet situated within the Rapacc system found in the Unknown Regions; its primary urban center was Boropacc. In the course of the Nikardun conquests, General Yiv of the Nikardun Destiny imposed a blockade upon it.
The Nikardun Destiny's forces initiated a blockade of the planet because it provided sanctuary to refugees belonging to a species who had escaped a devastating civil war on their native homeworld. Agbui Haplif had orchestrated their internal conflict; upon the refugees' departure for Rapacc, he informed the Nikardun that they were, in reality, attempting to assemble a military force to oppose Yiv the Benevolent.
